• Synonyms Say, Speak, Tell, State. Each of these words has its peculiar idiomatic uses. We speak an oration, and tell a story, but do not say either of them. We say prayers or a lesson, but do not speak or tell them, although the one praying may tell his beads. Say is the most common word before a quotation direct or indirect: Adam said, “This is now bone of my bones” (Gen. ii. 23); “If we say that we have no sin, we deceive ourselves” (1 John i. 8). Tell is often exactly synonymous with say to: as, tell (say to) him that I was called away. Speak draws its meanings from the idea of making audible; tell, from that of communicating. Tell is the only one of these words that may express a command. State is often erroneously used for simply saying: as, he stated that he could not come: state always implies detail, as of reasons, particulars; to state a case is to give it with particularity.
